Changan.

Li Zhong hugged Li Lizhen and sneezed.

This must be someone speaking ill of him behind his back.

This year, the Academy of Sciences has finally made great progress.

Steam Locomotive 1.0 (Toy Edition) should be coming out.

Two small cylinders the size of a palm have been made, and the entire steam locomotive is half a meter high, almost as high as a person's knees.

And then wide, so wide in the ass.

The big one can't be made, but the small one can still be made.

Now, Li Chong and Li Lizhi are at the Academy of Sciences, while baking a fire to keep warm, while waiting for the craftsman to splice the final rails.

"Dean, it's done!"

A craftsman came in and said with a crossed hand salute.

"Hmm!"

After hearing this, Li Chong also stood up and helped Li Lizhen up.

Then he went to the courtyard outside and said to the craftsmen, "Add water and heat it!"

"Whoa!"

This is followed by heating for up to half an hour.

Everybody was waiting for this thing to run.

Half an hour later......

Seeing that it seemed to be almost over, Li Chong asked the craftsman to start.

I saw that the miniature steam locomotive, which was originally stationary, slowly began to walk up with the push of the connecting rod of the cylinder.

When the craftsmen in the Academy of Sciences saw this scene, they couldn't help but clap their hands and stomp their feet and raise their arms and shout.

Because from Li Chong's proposal of the concept of steam locomotive to their realization, now, they themselves have forgotten how many years it is.

Li Lizhi was also a little shocked when she looked at this scene.

Because......

Have you ever seen someone who can run on their own without having to pull a horse?

The key is......

There was still a man sitting on it.

……

Next.

The small steam locomotive ran in the yard for an unknown number of laps.

Because everybody rides up and wants to try it.

Of course!

Li Zhong and Li Liqing forget it.

After all......

Both of them are people of status and status.

And......

To be honest, Li Chongting was worried.

After all, the security of this newly made thing has generally yet to be verified.

I'm afraid that when I run, I will blow up the cylinder for you.

But the good news is that after half a day, there is none.

……

Li Lizhi also asked curiously, "What is this?"

After marrying Li Chong for so long, she didn't even know that Li Chong was doing this kind of thing.

Li Chong said, "This is called a steam locomotive, and it is specially used to transport bulk goods. For example, coal, grain, iron ore, and so on. Of course, it can also be used to transport people."

Li Lizhen: "Uh...... But it's so small, and it's not a lot of luck, right? It feels like a couple of donkeys or a couple of horses."

Li Chong: "This is because this is a miniature version, and a large steam locomotive is too material-intensive, and the time period to build it is long, so let's build such a small one first and try the effect." This is just born before the full moon, and he came out on duty. It's good to grow up in the future!"

Of course!

Although the construction of a small steam locomotive is indeed a cause for celebration.

But......

They can't rejoice too soon.

Because with Datang's ironmaking output, it can't support how long the railroad tracks they lay are at all.

Next......

What they have to do is to slowly feed back to all walks of life.

For example, the iron industry is not without room for operation.

There is a very serious problem.

If it can be solved with human power, why bother to take coal from coal

It is dug out of the mine, transported to a special location, and then used to be converted into productivity.

Isn't the process of transportation in the middle of the process labor-intensive?

If Datang wants to produce an industrial revolution, it is not only a matter of invention, but also a matter of how easy it is to obtain fuel and how cost-effective it is.

After all......

In ancient China, everyone knew that sometimes manpower was cheaper than burning coal.

……

After the joy is over.

Li Zhong then asked the craftsmen to study a four-wheeled steam locomotive, which could be used to drive into the field, and a plow could be hung behind it.

It's good to make a cylinder with this, but it's just ......

This cylinder should be made relatively large, otherwise, it will not be able to move.

Li Lizhi stood beside Li Chong and watched Li Chong command the craftsmen to work, and felt that Li Chong was particularly reliable.

Also, what the hell is going on in his head. I want to make so many magical, unbelievable things.

The craftsmen all looked at the concept drawings of the cars that the dean had drawn for them.

If such a steam locomotive is made, will the people not need to farm in the future?

I saw Li Chongdao: "This should be more difficult than the previous one, especially the steering problem of the front wheels, but the others are almost the same, and the middle drive part can be tried directly with gears." Think about it, you can just drive the rear wheel to rotate anyway."

The general shape has already been drawn by Li Chongdu.

Fortunately, Li Chong has watched a lot of popular science videos, and he has never eaten pork, at least he has seen pigs running.

Even......

Li Zhong drew all the big flywheels for them.

For a while, the craftsman probably didn't understand why there was a big flywheel here, and to be honest, Li Chong didn't understand it either, but ......

Speculate with a scientific mind......

This must be a counterbalance.

If it weren't for this big flywheel, the car wouldn't be unbalanced when it was running.

After all......

This is a single-cylinder steam locomotive.

Li Zhong conservatively estimated that if this thing really came out, it was estimated that it would weigh at least a dozen tons, or even dozens of tons.

……

End of December.

Li Er finally returned to Chang'an.

As soon as he came back, Li Youmu immediately told Li Chong about what happened in Luoyang Palace.

Alas......

can only say, Li Er, isn't this nothing to fool around!

It almost scared his four sons.

Li Zhong asked Li Youmu, "Then what do you say in the end?"

Li Youmu said, "We didn't speak, but Wei Zheng came out to speak, saying why did Your Majesty embarrass the four children."

Li Chong: "And then?"

Li Youmu: "Then Your Majesty laughed, saying that we are not like Aye at all, and said that Aye, on the first day you saw Your Majesty, you asked for four beauties, that is, our A-Niang. What else to say, but it's not like Aye. After saying that, he seemed to be very emotional."

Li Chong: "And then?"

Youmu Lee: "And then ...... There will be no more."

Li Chong: "You, Aya, I'm asking about that little lady Wu. How's she, is she pretty?"

Youmu Lee: "......"

Li Youmu had to frown and look at himself Aye.

The next day.

Li Chong entered the palace to report on the steam locomotive, and after the report was finished, by the way, he had to count Li Erfan.

said, "Your Majesty has nothing to do with summoning the other party. Can't you let her live the rest of her life peacefully?"

However, maybe Li Chong also knows that for a restless person, it should be impossible to make her mediocre.
